[Relationship between jugular vein thrombosis and extremity vein thrombosis by vascular color Doppler ultrasound].

OBJECTIVE:To explore the relationship between jugular vein thrombosis and extremity vein thrombosis in cancer patients by vascular color Doppler ultrasound. METHODS:A total of 79 cases with malignant tumors complicated with venous thrombosis undergoing vascular color Doppler ultrasound were analyzed retrospectively. All cases were divided into the group of jugular vein thrombosis (n = 36) and the group of extremity vein thrombosis (n = 43). The thrombotic factors of PT (prothrombin time), APTT (activated partial thromboplastin time), FIB (fibrinogen), HCT (hematocrit), PLT (platelet), PCT (plateletcrit), PDW (platelet distribution width), MPV (mean platelet volume), pathologic type and thrombotic time were compared between two groups. RESULTS:Between two groups, significant differences existed in APTT, pathologic types and before or after therapy (P < 0.05). However the other factors were not significant (P > 0.05). CONCLUSION:The clinicians should pay great attention to malignant tumor complicated with venous thromboembolism (VTE). An early diagnosis is essential to prevent pulmonary embolism (PE) and improve patient survival. Vascular color Doppler ultrasound may be used as the first-line examination. Preoperative and postoperative prophylactic anticoagulant therapy can reduce the risk of VTE in patients with high-risk factors.
